Subject: vlan: Add support for net_devices_ops.ndo_fcoe_enable/_disable to VLAN
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0af46d997fcbfd25a9e166c2431bfebc03720a36;p=openwrt%2Fstaging%2Fblogic.git

vlan: Add support for net_devices_ops.ndo_fcoe_enable/_disable to VLAN

This adds implementation of the net_devices_ops.ndo_fcoe_enable/_disable to
the VLAN driver. It checks if the real_dev has support for ndo_fcoe_enable/
ndo_fcoe_disable and if so, passes on to call the associated real_dev.
